  Reasoned pruning

   Each action or inaction has an important influence on tree’s life, its lifespan, its mechanical resistance, its landscaped harmony, its health, briefly its future. 

Pruning has to do in a view of long-term management like tree’s sustainable nature. To ask to constraints of cohabitation between human and tree, we have different types of pruning. 


  • Formative pruning: this type of pruning consists in regular follow up of young trees in order to have a harmonious habit and anticipate potentially future mechanic weakness. In this way we reduce invasive interventions in the adult stage. That is the most reasonable pruning according to sustainable management. 
  • Maintenance pruning: it maintains tree into constraints we have chose at the end of formative pruning, restructuring pruning or conversion pruning. These constraints can be tree’s safety by ablation of died branches or maintain tree in structured habit or at the contrary in partially free habit. 
  • Adaptive pruning: it consists to adapt tree’s volume to any constraint: wire, building, vicinity, broken risks, etc. We have to avoid as far as possible that type of pruning thanks to formative pruning. Guying sometimes allows that type of pruning. 
  • Raising: it consists to answer to an esthetic constraint of landscaped harmony. Be careful, it can be justified but it never is good for health’s tree. 
  • Conversion pruning: health’s trees can sometimes necessity to totally modify its method of management. So we can decide to pass from a partially free habit to a tree in a structured habit or the contrary. In both of these cases each year a pruning maintenance will permanently be necessary. Guying sometimes allows that type of pruning which is so traumatic for trees. 
  • Restructuring pruning: it often concerns mutilated trees (storm, severe pruning…) or trees without structured management. So we progressively bring the tree to a structured habit.
